George Carlin ended his relationship with the MGM Grand in Las Vegas with a devastating diss the other night. The caustic comic finished his four-year run with a dark set that included riffs on suicides and beheadings, and made it clear that he couldn’t wait to get out of “this [bleeping] hotel” and Sin City. The Las Vegas Review-Journal’s Norm Clarke reports that Carlin told the crowd of 700 that he was looking forward to going back east “where the real people are.” He added, “People who go to Las Vegas, you’ve got to question their [bleeping] intellect . . . Traveling hundreds and thousands of miles to essentially give your money to a large corporation is kind of [bleeping] moronic. That’s what I’m always getting here is these kind of [bleeping] people with very limited intellects.” When a woman yelled something that sounded like “stop degrading us,” Carlin fired back, “Thank you very much, whatever that was. I hope it was positive; if not, well, [bleep] me,” using slang for oral sex. Strangely, though, Carlin isn’t ready to leave town yet: He’s jumping to the Stardust in February after a falling out with the MGM Grand.
